Abstract:
A method and concomitant apparatus for comprehensively representing video information in a manner facilitating indexing of the video information. Specifically, a method according to the invention comprises the steps of dividing a continuous video stream into a plurality of video scenes (610, 612); and at least one of the steps of dividing, using intra-scene motion analysis, at least one of the plurality of scenes into one or more layers steps (620); representing, as a mosaic, at least one of the plurality of scenes; computing, for at least one layer or scene, one or more content-related appearance attributes (630); and storing in a database, the content-related appearance attributes or said mosaic representations (630).
Abstract:
An electronic integrated circuit (10) which includes at least one of RF, microwave, digital and analog components (62) connected in a desired circuit. The integrated circuit includes a substrate of a conductive material (34) having on a surface thereof a body of a dielectric material. The dielectric body is formed of a plurality of layers of the dielectric material bonded together (16). A plurality of strips of a conductive material are on the surfaces of the layers of the body to form RF, analog and digital components. Discrete electronic devices are mounted on the body and connected in the circuit. Vias of a conductive material extend through the various layers of the body to electrically connect the various strips of conductive material on the layers of the body.
Abstract:
A receiver (100) for demodulating multiple digital modulation formats including vestigial sideband (VSB), quadrature amplitude modulation (QAM), and offset QAM (OQAM). The receiver includes a timing recovery circuit (126) that produces accurate timing information for each modulation format and a signal processor (54) for adaptive equalization and quantization of each modulation format. The signal processor includes an adaptive equalizer (900) which is a passband equalizer that performs blind equalization using a feed forward equalizer (902) and a decision feedback equalizer (910).
Abstract:
A command and control architecture for a compressed digital television broadcast studio (100). The architecture includes provisions for session management, real-time control of studio activities, the use of proxy objects to establish communications with objects not providing a high level of control, control of studio filter devices (154) and stream management. The invention includes an object architecture particularly suited to the digital studio.
Abstract:
Spherical particles of fluoride up-converter phosphors having a particle size of 1 micron and less can be made from their corresponding precursor hydroxycarbonate particles by heating the hydroxycarbonate particles in an oxygen-containing atmosphere to convert the hydroxycarbonate to the corresponding oxide but without changing the size and shape of the particles, and then heating the phosphor oxide particles to their corresponding fluoride particles by heating in SF6, at a temperature that will crack the SF6 but will not change the size or shape of the phosphor particles.
Abstract:
The invention provides an apportioning system comprising a first apportioning chamber (19) having a first outlet (1413) and fillable with liquid to a first defined level (1412) such that if liquid is added to fill the first apportioning chamber (19) above the first defined level (1412), the extra fluid drains through the first outlet (1413), an inlet channel (1404, 1411) that distributes liquid to the first apportioning chamber (19), and a first electrode-based pump (1409) for moving liquid in the first apportioning chamber (19) out the first outlet (1413).
Abstract:
A method and apparatus for predicting how any given spatio-temporal light distribution would change an observer's pupil diameter. The method generates the instantaneous effect of luminance driving the pupil diameter, the cumulative driving function of the pupil diameter, and the evolving pupil diameter. Using the evolving pupil diameter together with the input luminance, the method computes the retinal illuminance distribution for the given input illuminance. The method is implemented as a software routine executed by a general purpose computer.
Abstract:
An electronic circuit (12) including an enclosed housing (26) having an electronic circuit therein and which is filled with an electrolyte which forms a battery for operating the electronic circuit. The device may also include a speaker (24) and a microphone (22) which are in the housing and connected to the electronic circuit to form a hearing aid.
Abstract:
A hearing aid (10) includes an electronic assembly (12) mounted in a cylindrical shell (14) with the shell (14) being mounted in an opening in an ear mold (16). The electronics assembly (12) inclludes a printed circuit strip (26) having thereon a speaker (22), a microphone (18) and electronic components forming a signal processing circuit (20) for amplifying the sound. The ear mold is of a soft, durable and compliant material so that it will fit tightly in the ear of a user. The hearing aid is of optimum design having a minimum number of components and is easy to assemble on an automatic basis. This provides a hearing aid which is relatively inexpensive so as to be disposable.
